PAPER-MAKING APPARATUS.

Specification of Letters Patent.

Application filed Gctober 8, 1913.

Patented Nov, 149, 191d. Serial No. 794,101.

To all whom it may concern Be it known that I, SOLOMON R. Waco, a citizen of the United States, residing at Appleton, in the county of Outagamie and State of WVisconsin, have invented new and useful Improvements in Paper-Making Apparatus, of which the following is a spoolfication.

The present invention has reference to paper-making apparatus, and more espe cially to apparatus for reeling or winding up the web of paper after the same has been passed through the size bath and before it is subjected to the final drying. It comprehends the provision of improved devices for regulating the speed of the winder proper and the tension exerted upon the web during winding.

An embodiment of the invention is illustrated in the accompanying drawing, whereof:

Figure l is a diagrammatic side elevation of the complete apparatus; Fig. 2 is an enlarged side elevation of the winding mechanism; Fig. 3 is a plan view of Fig. 2; Fig. 4 is a plan view on an enlarged scale of the winding drum; and Fig. 5 is a plan view likewise on an enlarged scale of the spreading rack.

In said drawing, 1 indicates, generally, the strip or web of paper undergoing treatment, and 2 the bath of gelatin or other size through which the same is passed as the initial step of such treatment. This web, which has previously been subjected to the usual, preliminary sizing, with or without mordants, may be led to the gelatin bath either directly from the machine, or after it hasfirst been reeled up in a dry state.

On leaving the size bath, the web is passed between the rolls 3 and 4:, which serve both to feed it forward and to remove the excess size, and from these rolls it is led while still wet, to the winding mechanism. The latter preferably consists of a rotating drum 5, whose shaft 6 has a cone or other suitable drive 7, and areel 8 to which the web is fed from the drum.

The two rolls 3 and 4 have ordinarily a definite surface speed, which is approximately one hundred feet per minute, as is generally understood, and since the drum must rotate in unison with said rolls, the provision of a take-up device is most important. This device may advantageously comprise a l1orizontallyarranged risingand-falling roll 9, the shaft ends or trunnions of which are movable in vertical slots 10 formed in a frame 11 and are connected by chains or other flexible elements 12 with the shaft ends or trunnions of a second rising-and-falling roll 13 that acts under certain conditions, as a weight for roll 9 and is mounted in said frame beneath said roll, with its shaft ends or trunnions likewise extending into said slots and normally supported upon the bottom thereof. The web passes over guide rolls l4 and 15 on its way to roll 9, and is led from the latter over avguide roll 16, and thence across a rack 17 to the drum, the arrangement being suchthat the pull exerted by the drum upon the web, due to its speed, controls the movemcnt of the upper roll 9, the latter, when raised a distance greater than the length of the chains 12, drawing the lower roll 13 upwardly with it, in which case the weight of roll 13 is added to that of roll 9, with a resultant increase in the tension.

exerted upon the web.

The rack and drum are constructed with the special object of completely smoothing out and thus removing all wrinkles, creases, puckers and the like in the web. To this end, the rack is composed of V-shaped rods or bars 18 which are arranged transversely of the machine in spaced, parallel relation to one another, and havetheir arms or members of equal length and disposed at obtuse angles, while the surface of the drum is formed with similarly shaped and arranged grooves 20. The rack bars 18 are located at a greater distance apart than the drum grooves, and they are supported by connecting bars 19 which constitute the end pieces of the rack and are themselves mounted in any desired manner.

The two sets of angular bars and grooves just described have their apices directed toward the winding reel 8, and in consequence of their particular arrangement, they exercise a spreading and smoothing action upon the web. Also, the spaces between the bars and grooves permit fine wrinkles and creases in the web to enter thereinto, thus avoiding crushing of the web during its passage between the drum and the reel.

The aforementioned reel 8 is preferably so mounted as to enable it to be raised or lowered, according as the tension exerted upon the web during winding is to be increased or reduced. In the construction illustrated, the reel has an adjustable sup port comprising a pair of upwardly inclined arms 21, which are pivoted at their lower ends to the drum support and are connected at their upper or outer ends by adjustable links 22 to the corresponding ends of a pair of inclined arms 23 fixed to a horizontal shaft 24. This shaft is actuated from a vertical controller shaft 25 through the intermediary of worm gearing 26, the shaft 25 being equipped with a hand-wheel or other operating device 27. Rotation of the controller shaft thus effects a corresponding movement of shaft 24/. and, in consequence, a rocking movement of arms 23 with the result that the inclination of the reel-carrying arms 21 is varied.

After the reel has been filled, it is removed from its support, with the web in a wet state thereon, and deposited upon a frame 28 where it is allowed to remain for a period which may vary from one to twelve hours, during which step the web is subjected to a very extended and gradual permeation by the gelatin. In consequence, the tensile strength as well as the ink-resisting property of the paper are increased, while at the same time, the sizes are enabled to set and a union, so to speak, is produced between the same and the mordants. The web is kept wet during this period of rest by being wrapped with wet cloths, or in any other desired manner.

After resting in the manner just described, the web, while still wet, is unreeled and passed over a series of drying rolls 29 of any suitable or preferred type. It will be understood, therefore, that this final drying does not take place until the period of rest has been completed, during which period the gelatin continues to soak into and be absorbed by the web, and for this reason the heating and drying are suiiiciently remote from the time of immersion in the gelatin bath to work any injury upon the paper.

The aforementioned frame whereon the wet roll of paper is allowed to rest may be of any suitable construction, but is preferably sufficiently large to enable a number of rolls to be supported thereon at the same time. Also, the rolls may be moved in order through this frame, the paper on the roll at one end of the frame being unreeled and led over the drying rollers. The roll at the other end of the frame is that one which has just been removed from its support in the winding mechanism, it being replaced by the previously emptied reel from the first mentioned end 6 of the frame,
